The phrasal verb "walk out on" is predominantly used in informal contexts, often found in everyday conversation rather than formal writing or speech. This phrasal verb generally means to leave someone or something abruptly, especially when referring to abandoning responsibilities or relationships, such as a partner, family, job, or obligations. For example, one might say, "He walked out on his family," indicating he left them without notice. It carries a connotation of responsibility being neglected in the action of leaving. While "walk out on" might occasionally appear in less formal written outlets such as blogs, personal narratives, or cinematic dialogue, it is not typically employed in professional or academic contexts. The expression suggests a sudden departure and often implies desertion or betrayal, thereby carrying an emotionally charged implication.
